calculate the first four energy levels of an ethane (C2H6) molecule in a box with one finite wall if the box length is the smaller pore size of Zeolite-A used for cracking hydrocarbons (L = 1.5 ). Let the potential of the finite wall be 0.01 eV. ii) Now, compare these to the energy levels the ethane molecule would have if both walls of the box were infinite and discuss the origin of the difference that you observe. Hint: you will need to refer to the lecture notes to answer this and the next question. Be sure to check that you using SI units for all energy, mass, et cetera.
